Description
Mizutani Scissors - BLACK-SMITH Solid
Two professors of Ergonomics and Metal Engineering conducted an analysis that resulted in the BLACK-SMITH Solid. These scissors feature a center of gravity situated close to the hand to reduce wobbling while cutting. Additionally, a carefully controlled hardening process brings out the ideal properties of the materials, rendering it the ideal all-purpose scissors. For barbering, the 6.5 and 7.0 sizes are particularly recommended.

BLACK-SMITH Solid utilizes the advanced Extramarise® Processing, a distinct hardening technique driven by precise temperature management. This method optimizes the qualities of the materials, while giving the scissors the required hardness and durability. Following a collaboration with metallic engineering specialist Dr. Asakura, our team studied the original material of the SOLID after applying the suitable heat treatment. The comparison between the treated and non-treated materials was striking: the analysis showed that heat treatments can extend the working lifespan of scissors significantly.

EXTRAMARISE
-
EXTRAMARISE® is a MIZUTANI-developed heat treatment specifically designed for scissors. It uses the perfect temperature required to bring out the most out of special materials like cobalt, molybdenum, vanadium, etc. and create a blade with the ideal strength for haircutting. The performance of any material depends on the heat treatment, which is why the company's proprietary approach (*hardening, tempering, sub-zero processing) is essential. In fact, the process has been carefully crafted to benefit from long years of data and experience. EXTRAMARISE® processing is the ultimate heat treatment for scissors.

BALL BEARING
These high-precision metal ball bearings are produced in Japan and boast superior anti-corrosion characteristics compared to foreign-made items. With decreased friction around the screws, they lessen strain on the hands while also protecting the blade from damage, resulting in a longer operational lifespan. -
